@Lindagaf I think it’s a fine line. Your daughter clearly chased after the course b/c of an inherent hunger to learn – and it was corroborated in other areas of her app. The tippy top colleges are wary of the test taking drone who seems to only relish blandishment of resume/transcript and GPA. The colleges don’t want to contribute to the “arms race” mentality that some kids feel is required to be a viable applicant.
To the OP, I’d say look at your options – are there interesting ECs that you’d rather devote yourself to more? If so, then do those and eschew the self-studied AP courses.
